some good picks there though (and some awful ones, forrest gump?)
there was one of these threads in the music section which was pick the best album from every year youve been alive which might be easier to do.

It's also too difficult, take for example 1928, and you have The Crowd, October, Passion of Joan d'Arc and The Wind. I just imagine myself pickin a film from 1959 (one of the few year i know well) and my head explode

It can be like Hanoi said of we can pick 10 films for decade. Is more easy in that way and you don't forze people to let infinte of years in blank

I don't want to do it to way back to the 20's but i will do a few years worth. And I am not doing a lot of research on this, I am just typing "[Year] Movies" into google and I'm looking my favorite out of the ones I've seen.
